portable handair pum to the carrying of various auxiliary artic es therein, such as ll tools, etc.; and all the auxiliary articles can be easily taken along by the cyclist when he is leaving the bicycle or motorcycle. I

The invention will be best understood from a consideration of the following del tailed description taken in connection with T the accompanying drawings forming a (part of this s ecification with the understan ing that whi e on the drawing one embodiment of the invention is disclosed, the invention is not confined to any strict conformity with the showing 'ofthe drawings, but may be embodied in any manner which does not make a materialdeparture from thesalient features of the invention. a

t Fig. 1 shown the improved air a central longitudinal section.

Fig. 2 is a central section taken at an angle of 90 with regard to. the section "shown in Fig. 1. l

Fig. 3 is a plan view of Fig. 1. f

The piston. 1 which serves as a receptacle has at its lower end a leather cup 2 audit "isfolosed at the upper end bya removable 40 lid 3. "The piston 1 is large inpro ortion' to its depth so that all the common y. used auxiliary articles may be stored in the same. Onthe u per end ofthe outside of the side walls oi the iston l two handlesd are 46 hinge'dly mounted so that theymay be laid down from the position of use shown in Figs. 1 and 2 into the osition shown in dash lines in order'to' re ucethe length of the pump. a The ump barrel 5 has at its 50 u per end; a gui eacap 6 for guiding the pieton 1. This guide cap is preferably fixed ermany, have invented cer-.

' shape of a flat pocketbook or billfoldpump I Intestimonywhereof I afiix my si by riveting. The umpbarrel has an air T holev 7 and an ori ce 8 in a nipple 9 for connecting the um with a pneumatic tire bymeans of a exi le tube.

It is to be noted that the pump barrel 5 and receptacle-forming piston 1 are not'only of relatively. large cross section and short length,but that, as a feature of the invention, they are of oblong cross section or flattened so that the longer transverse dimension on width of the piston 1 is just sufficient to' enable it to receive the auxiliary article of greatest widthfwhich may be a spanner, and toreceive all of such articles compactly. y

' Thus all of the usual tools and other aux- I iliary articles may be. conveniently stored within the air pump, without the need of having, as commonly a separate or'special receptacle or bag. T e air uinp of the present invention, withthe other auxiliary articles contained therein, may be conveniently carried on the vehicle,or may be removed therefrom and conveniently 'carriedwfl away by the owner,to prevent theft or unauthorized use of an of the auxiliary artieles;it'being noted inthis connection that the pump as a whole has substantially the I claim: T T p A portable handair pump comprising a V barre a tubular piston reciprocating in said barrel,1clo sedat its inner end, and having a removable closure at its outer end, a plurality of handle bail members hinged to the sides of the outer end of thepiston, movable to positions to closure and also mova le towardono another ermit removal of the across the end of-the iston to serve together as an operating han 1e for the piston, said members when in the last-named position locking said closure to the piston, whereby the motion-of the loose contents of the chamber ofthe piston cannot loosen or knock .95
